Choosing the Size and Wood

Before you delve into building your DIY sauna, a critical first step is determining the dimensions that'll best fit your space and selecting the ideal wood type.

Deciding on the dimensions

Selecting the right dimensions revolves around two primary aspects: how many people will use it and the space you can dedicate to it. A compact design, such as a 6' diameter by 5' length, is ideal for two users and requires roughly 1,200 board feet of routing and 42 routing strips.

This size offers an optimal balance between comfort inside the sauna and efficient use of available outdoor or indoor space.

If you plan on inviting over more friends to enjoy your new sauna, consider expanding its dimensions accordingly. Size affects not just capacity but also heat distribution - larger saunas might require proportionally stronger heaters.

However, don't forget that bigger sizes demand more materials during construction and increase the occupied footprint in your layout.

Best wood options for DIY barrel sauna plans

Selecting the right type of wood for your barrel sauna is crucial. It not only determines the longevity of your sauna but also its performance and appearance. Here are some top choices:

1. Clear Cedar: This type has a smooth surface devoid of knots, delivering a sleek appearance to your sauna. Known for its natural resistance to moisture and temperature changes, it is an excellent option for constructing barrel saunas.
2. Knotty Cedar: While it might not be as visually appealing due to various knots, it is still quite durable and resistant to insects, which makes it another great choice.
3. Western Red Cedar: Whether in a clear or tightly knotted form, this type has superior resistance against water damage and insects.
4. Pine: Although not as strong in terms of resistance to weather elements and bugs, pine offers a more affordable yet still effective option if you're on a tight budget.

Tools and Materials You Will Need

To build a barrel sauna, gather essential tools such as a circular saw, drill, router with cove and dado bits, tape measure, pencil for marking lines. For materials, you will need top-quality wood like cedar or redwood, metal bands or rope for tightening the assembly, clear sealant to protect the wood from damage.

Additionally prepare insulation and your chosen sauna heater. Be sure everything is on hand before starting to streamline the building process.

Required tools

To successfully build your barrel sauna from scratch, you need to have the right tools at your disposal. Here's what you will need:

1. A power drill for boring holes.
2. Several high - quality saws, including a circular saw and a table saw.
3. Router with bead and cove router bits to create tongue and groove joints.
4. A hammer for securing parts together.
5. A level to ensure all parts are properly aligned during assembly.
6. Tape measure for accurate measurements throughout the process.
7. Screwdriver or  screwdriver for attaching components together.
8. Sandpaper or an electric sander to smooth out any rough surfaces on the wood.

Necessary materials

Preparing for your custom barrel sauna project requires gathering all necessary materials upfront. Here's a list of indispensable items you will need:

1. Stave stock: You can typically find this as 2x6 lumber. The quantity depends on the size of your sauna.
2. Tongue and groove paneling: This material will serve as the walls of your sauna.
3. Insulation: To keep the heat in, opt for quality insulation material that withstands high temperatures.
4. Roofing materials: Choose weather-resistant options, especially if you plan to install an outdoor barrel sauna.
5. Sauna door: A custom or pre-made door is essential to enclose your sauna environment.
6. Nails and screws: These fasten all sauna components together for a well-constructed build.
7. Accessories: Consider adding benches, hooks for towels, and even electric heaters for optimal comfort.

Wood Burning or Electric Sauna? Choose your kind of sauna

When it comes to choosing between a wood-burning sauna or an electric sauna, it largely depends on personal preference and circumstances.

The wood-burning sauna offers a traditional and authentic experience, with a crackling fire and the smell of burning wood creating a cozy and relaxing atmosphere. It also provides a drier heat, allowing for a deeper sweat and detoxification. 

However, you will need to install a chimney or ventilation shaft to prevent smoke buildup. It's also more difficult to control the temperature.

On the other hand, electric is more convenient and easier to manage, as they require no preheating or monitoring of the fire. With just a flip of a switch, the electric heater quickly heats up the sauna to the desired temperature.

Additionally, electric is more energy-efficient and can be used in locations where wood-burning saunas may not be feasible, such as urban areas with strict fire regulations. However you will need to run weatherproof power to it.

Ultimately, the decision between a wood-burning or electric sauna comes down to personal preference, convenience, and the desired sauna experience. 

Build your Sauna Base 

If you're thinking of building a backyard sauna, one of the most important aspects to consider is the base. The base serves as the foundation for your sauna and provides stability and support.

There are a few different options when it comes to choosing a base for your sauna. One popular choice is to build a concrete base. This provides a solid and durable foundation for your sauna and can be easily leveled.

Another option is to use a wooden base. This can be a more affordable option and gives a natural and rustic look to your sauna. However, it's important to ensure that the wood is properly treated to prevent rot and moisture damage.

Whichever type of base you choose, it's crucial to make sure it is level and well-insulated to prevent heat loss. 

Taking the time to build a sturdy and well-prepared base will ensure that your sauna lasts for years to come. 

Building the Barrel Sauna: Part 1

Start by preparing the staves, which are crucial components for the shape of your sauna. Next, work on creating dado joints to reinforce the structure and ensure its stability.

Preparing the staves

Selecting and preparing the staves establishes the foundation of your custom barrel sauna. Here's a simple process to follow:

1. Choose western red cedar: Considered the best wood for saunas, it is durable and resistant to decay.
2. Decide on stave size: The sizes vary but common measurements are 1 ½” thick by 4” wide by approximately 6 feet long.
3. Create the barrel shape: Use a bead and cove joint router bits to cut two convex edges on each stave, allowing them to interlock seamlessly.
4. Assemble the staves in order: This assembly forms an interlocking system accommodating natural expansion and contraction.
5. Apply finishes if desired: Although optional, you may consider applying wood preservative or paint to prolong your sauna's lifespan.

Creating the dado joints

Crafting the dado joints is a pivotal step in your DIY barrel project. Follow these steps to ensure successful execution:

1. First, be aware that the challenge lies in making accurate dado cuts into all your staves.
2. Once you've decided on the sauna's size and design of a barrel sauna, measure and mark each stave where the cuts need to be made.
3. Use dado blades on a table saw or circular saw to cut out notches from each marked point. Make sure it’s done accurately as this will affect how well your staves fit together.
4. After all the cuts are made, line them up and test their fit by temporarily assembling some parts of your new sauna.
5. If any adjustments are needed, make them before proceeding with assembling your sauna.

Building the Barrel Sauna: Part 2

Now that the staves are set, let's dive into Part 2 where we'll tackle constructing end caps, installing the door and assembling cradles for your barrel sauna.
